Server Commands
78 IOLAN Device Server User’s Guide, Version 1.0
Set Service
prompt-with-name
Displays the Server Name field value instead of default product name. When enabled,
the Server Name is displayed in the Device Server login prompt, CLI prompt,
WebManager login screen, and the heading of the Menu. The default value is Off .
single-telnet
Sets all reverse connections (raw and telnet) to a one connection at a time mode.
Server-side applications will get a (socket) connection refused until:
z All data from previous connections on that serial port has drained
z There are no other connections
z Up to a 1 second interconnection poll timer has expired
This also enables a per-connection keepalive TCP keepalive feature. After
approximately 3 minutes of network connection idle time, the connection will send a
gratuitous ACK to the network peer, thus either ensuring the connection stays active
OR causing a dropped connection condition to be recognised by the reverse service (all
connections).
Applications using Single Telnet need to be aware that there can be some considerable
delay between a network disconnection and the port being available for the next
connection attempt; this is to allow any data sent on prior connections to be transmitted
out of the serial port. Application network retry logic needs to accommodate this
feature. The default value is Off .
subnet-bit-length
The number of bits in the subnet mask. For example, a subnet mask of 255.255.0.0
has 16 subnet/prefix bits. Valid values are 0-31. The default is 0. When the value is 0,
the correct value is determined based on the class of the IP Address.
retry
The number of times the Device Server will attempt to transfer (using TFTP) a file
to/from a host. Enter a value between 0 and 5. The default is 5. A value of 0 (zero)
means that the Device Server will not attempt a retry should TFTP fail.
timeout
The time, in seconds, that the Device Server will wait for a successful transmit or
receipt of TFTP packets before retrying a TFTP transfer. Enter a value between 3 and
10. The default is 3 seconds.
